Worried about new job. Just need some support.

Hey guys, I'm (22F) starting a new job as a student lending advisor at a large bank this summer. The role involves 50-70 inbound/outbound calls per day, helping borrowers with loan questions and some cross-selling.

My biggest concern is that my social anxiety affects my listening skills — I get so caught up in the anxiety of the interaction that I'm not fully absorbing what the person is saying. I'm also worried about how to handle angry customers. I tend to lock up when I'm in a tense situation with someone.

Has anyone dealt with something similar in a call center or phone-heavy role? Any tips for staying present and focused during calls?
